What we've learned shipping production systems. AI, architecture, and 25 years of pattern recognition.

Before spending on fine-tuning, we measured whether a 1.7k-word AI constitution actually produces different behavior than a 29k-word one. The cheap probe answered it, and located the bottleneck.

A wind and solar forecaster we built on the side, mostly by pointing AI agents at the problem, is now live in production on Predico, the platform used by Belgium's grid operator, and gets scored against professional forecasters. Here is the honest scorecard, losses included.
Jul 11, 2026
We stress-tested whether a compact 6-principle AI constitution (Kardia) and Anthropic's ~29,000-word hierarchy actually pick different answers — using two independent strong judges. The divergence is real; the story about where it lives is judge-dependent. An honest interim report.
Jul 11, 2026
Before fine-tuning anything, we measured whether Kardia's short Citadel constitution and Anthropic's long hierarchy constitution encode different preferences on the same response pairs. Weak judges hid the signal; strong cross-family judges found a thin, real gap — about 17% opposite picks on a hard probe set. Method, confounds, and what we are not claiming.

We gave Claude Code a single /goal prompt. It recovered a 1997 undergraduate thesis from the Internet Archive, ported its solver, built a classic Mastermind board, and published it — with its thought process included.

Augur forecasts wind and solar for three European countries and scores every forecast against the grid operator's own — including where it loses. Why the baseline you beat is the whole story, and what honest energy forecasting actually looks like.

What happens when an AI agent reads a scenario document and executes it on a real iOS simulator — adapting to layout shifts, verifying with screenshots, and writing the report itself.

Your team ships 5x the code. Who's checking it? AI-generated code has specific failure modes that junior engineers can't catch. Here's the honest picture.
